CONSTRUCTION OF PIERHEAD SECTIONS

The type 1 pierhead section makes use of four internal spudwells. This section is also equipped with support brackets to receive the side connectors used to join these sections side to side with type 3 pierhead sections.

The _type 2 pierhead section contains six internal spudwells. Support brackets for side connectors are also used in this type. Additionally, the type 2 section contains six reinforced PI pontoons.

The type 3 pierhead section uses four internal and three external spudwells. Support brackets must be also added to support the side connectors.

The type 4 pierhead section, which supports the container handling crane, contains seven internal and three external spudwells. Six reinforced PI pontoons are also included.

CONSTRUCTION OF FENDER SECTIONS

A fender section is a 1'x15' structure incorporating three fender spudwells (fig. 10-40). Fender piles are driven through the fender spudwells after the causeway is elevated (fig. 10-41). The fender section can then rise and fall on' the piling. A series of foam-filled fenders are strung on the outboard side of the fender system to absorb impact from lighterage. Since it is only one pontoon wide, the fender system uses P5 pontoons as end-to-end connections instead of the P8.
